Mastering RMI

I bought this book for Rickard Oberg's reputation, which cost me [amount]. When I completed reading the book, I hardly believe the author is Richard Oberg. Most of books I read about RMI are better written than this book. The chapters about EJB and JINI are even worse. All the book is about the introduction of RMI and EJB and JINI....

A Book By Someone Who Really Understands RMI

To keep up on EJB developments, I follow an online EJB architecture discussion group sponsored by Sun. It includes most of the leading EJB technical gurus. Early on, a newbie wrote in to ask how best to get up to speed on EJB programming. Someone in the group replied with a short list. The first item on the list was: "Read everything Rickard Oberg writes." It impressed me at the time, since Rickard was a student and not the CTO of some leading EJB application server company. As time passed, however, and Oberg offered advice and provided coded solutions for more and more of the complex problems the group considered, I decided that the comment was absolutely correct. If you are a Java programmer, or want to be a Java programmer, and want to understand how really skilled Java programmers approach Java and EJB problems: Read everything Rickard Oberg writes.

A good tutorial for RMI, but...

I purchased this book after doing some research into RMI via the internet to give me a more solid understanding of RMI, which it did. However, when applying my acquired knowledge to a real-world application, I found that I was missing a HUGE piece of the RMI puzzle. RMI over the INTRAnet is a wonderful thing; however, when trying to implmenent RMI over the INTERnet, and the RMI server is behind a firewall, you are in for a painful migraine. This is a show-stopper for my employers, I wish that the book mentioned something about RMI and firewalls. There are workarounds for the firewall, but they are by no means easy and you will not find them in this book.
